问题 Is it possible to change the Motherboard serialNumber value with WMI? $SN = Get-WmiObject Win32_BaseBoard $SN.SerialNumber="123456" $SN.put() $SN.SerialNumber The error I got was: Exception calling "Put" with "0" argument(s): "Provider is not capable of the attempted operation " 回答1: In short no. I wouldnt expect that to work. The properties of Win32_BaseBoard are read-only as per MSDN SerialNumber Data type: string Access type: Read-only Assuming your BIOS supports it, in most cases, you

问题 I am trying to put together a list which shows all LogicalDisk instances in my Computer System and the drive letters they have been associated with. Coding is in C#. The WMI classes Win32_LogicalDiskToPartition , Win32_DiskPartition and Win32_LogicalDisk appeared to be the right data sources to get that Job done: Win32_LogicalDiskToPartition contains the property " Antecedent " which obviously links to a " DeviceId " property of class Win32_DiskPartition and Win32_LogicalDiskToPartition

问题 When requesting Win32_WinSAT from a x64 process I get the correct results (WinSATAssessmentState = 1), but when executed from a x86 I get "results not available" (WinSATAssessmentState = 3) x64 Powershell: PS C:\Users\alive> gwmi Win32_WinSAT __GENUS : 2 __CLASS : Win32_WinSAT __SUPERCLASS : __DYNASTY : Win32_WinSAT __RELPATH : Win32_WinSAT.TimeTaken="MostRecentAssessment" __PROPERTY_COUNT : 8 __DERIVATION : {} __SERVER : COMPNAME __NAMESPACE : root\cimv2 __PATH : \\COMPNAME\root\cimv2:Win32

问题 I can use the following WMI query to determine any DNS servers my machine might be using: SELECT DNSServerSearchOrder FROM Win32_NetworkAdapterConfiguration However, the following query I wrote to ignore null entries is invalid and I don't know why: SELECT DNSServerSearchOrder FROM Win32_NetworkAdapterConfiguration WHERE DNSServerSearchOrder!=null Is there a way to filter out the null entries? 回答1: The WQL language supports != and the IS [NOT] NULL syntax, the problem is the property which

问题 I'm writing a script on HYPER-V host for getting VMs guest informations. Is there a way to get VMs Operating System name from Hyper-V using powershell? There are several examples using (Get-WmiObject Win32_OperatingSystem -ComputerName $vmName).name but i should get this information directly from Hyper-V because of domain restrictions. Also i'm using hyper-v module of powershell but i couldn't see any cmdlets related to OS. 回答1: This could be retrieved from guest intrinsic exchange items. #

问题 I am able to query WMI classes and registry values using System.Management and StdRegProv (for registry). I want to move over to using Microsoft.Management.Infrastructure instead of System.Management. So far With help from lot of articles on the net, I can do a CIMSession and get the WMI classes (e.g. Win32_OperatingSystem) etc. with code as below using Microsoft.Management.Infrastructure; ... string Namespace = @"root\cimv2"; string OSQuery = "SELECT * FROM Win32_OperatingSystem"; CimSession
